Miller Adam W 4/A

What Happened

• Adam W. Miller, CEO and director of Knight‑Swift Transportation Holdings (KNX), had 17,758 restricted stock units convert into 17,758 shares on March 12, 2026. Of those shares, 7,699 were withheld/sold to cover tax withholding at $55.10 per share, generating $424,215. The filing is amended to reflect a joint account.

Context

• This was not an open‑market purchase but the conversion/issuance of performance-based restricted stock units with shares withheld to satisfy tax obligations — a routine administrative transaction common for equity awards. Such withholdings and sales to cover taxes do not necessarily signal the insider’s market view.
